John,
Without the intention of trying to egg on this debate (I'm really not), I feel like I want to speak my part, being on the other end of the spectrum as you. Coming from a place of learning, I (and many others on this site and this thread) are trying to wrap out minds around what you say vs what the manual says. I, knowing your background and having spoken with you on more than one occasion, put a LOT of stock into what you say, the advice you give. 99.999999% of the stuff that comes out of your mouth and through your keyboard, I (and, again, most on this site) believe without second guessing. However, when a manual written by the manufacturer says to do one thing and you say do another, that instantly creates a conflict in our minds. We want to trust both of you, and why shouldn't we? But, since you are both speaking opposite arguments, we have a hard time deciding what to do. We are all just trying to learn here. Please don't take the people who are "arguing" with you the wrong way; they trust you (at least I believe they do), but they also trust Kohler. IDK, maybe they are looking for proof beyond "I work on engines". Maybe they have searched around other forums and heard the "half throttle then off" advice. Maybe they just don't believe you. Maybe they don't believe Kohler. Honestly, IDK. I just see this thread going down a bad road and don't want you or anyone else taking things the wrong way.
That's it, that's my peace keeping speel
Oh, and for what it's worth: I, for one, let my Command idle for a couple minutes to cool down, then rev to about half throttle and shut it off. Since I've been doing this, I've never had a problem. Is it the right way to do it? Depends who you ask. With the K series, the Mag's, etc, I idle for a few minutes, then shut down at idle.
